# syntax=docker/dockerfile:1
#
# Developer station: Neovim (LazyVim) with nvim-dap configured to connect
# to a codelldb DAP server running on the "remote" container.
#
# Builds the newest Neovim from source (Alpine uses musl, so prebuilt
# glibc binaries don't run here) and layers on LazyVim, Catppuccin, and
# the nvim-dap plugin stack.  codelldb itself lives on the remote container.
#
# Build (run from repository root):
#   docker build -t dap-debug-dev -f devstation/Dockerfile .
#
# Pin a specific Neovim release:
#   docker build --build-arg NVIM_REF=v0.12.3 -t dap-debug-dev -f devstation/Dockerfile .
